tools: use the shared dbus client bindings for kete
Since most of the signals are propagated by the bindings we largely just need to hook up simple methods to log what is happening. One nasty hack: we import some of the bits into the kete namespace so tuhi-live continues to work. This can be fixed up in a follow-up commit. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
